Overview

What is this animal?

  • The Syrian, also called the golden or teddy bear hamster, is the largest and most commonly kept pet hamster.
  • It is calm and easy to tame, which makes it a popular first small pet, but it is routinely housed in cages far too small for its needs.
  • Syrians are nocturnal and territorial.
Show 2 more
  • Adults must live alone, as pairing them leads to severe fighting and death.
  • With patient, regular handling they become docile and tolerant of gentle interaction.

Temperament

  • Syrians are generally placid, slow-moving, and among the easiest hamsters to hold once tamed.
  • They are best handled in the evening when naturally awake, as waking a sleeping hamster can provoke a defensive nip.
Show 2 more
  • They bond through routine and food-based trust rather than cuddling.
  • Each animal has its own personality, but most settle into calm, predictable companions for gentle older children and adults.

A good fit for

  • First-time small-pet keepers
  • People wanting one solo pet with low running costs
  • Gentle older children with supervision
  • Evening and night-active households

Common mistakes to avoid

  • Housing two together, which causes fatal fights
  • Cages under 11 square feet of unbroken floor
  • Wheels under 12 in, risking spinal curving
  • Ignoring wet tail, a fast-killing illness

Enclosure

Minimum 11 sq ft of floor · 49 x 31 in

Must be housed alone. Strictly solitary

  • Provide at least 10.8 sq ft of continuous, unbroken floor, for example 49 x 31 in, with larger being better.
  • That is the size TVT, the German veterinary association for animal welfare, and Swiss Animal Protection recommend for a Syrian, because studies show golden hamsters do better from 11 square feet; the 39 x 20 in many guides print is the floor no hamster should go below.
  • Fill it with deep bedding of 16 in or more so the hamster can build natural burrows: TVT prefers 16 in and never less than 10 in, and Swiss Animal Protection asks for at least 16 in.
Show 5 more
  • Holding that depth takes solid sides about 20 in high, in an enclosure at least 24 in tall.
  • A solid (not wire) running wheel of at least 12 in diameter is essential to prevent spinal curvature.
  • Keep the enclosure at 64-75°F, away from drafts and direct sun.
  • Avoid poorly ventilated tube systems.
  • Include a sand bath, hides, and plenty of chews and forage to discourage bar-biting and stress.

Care in depth

Diet

Granivore/omnivore hamster mix
  • Feed a quality grain-based hamster mix of varied seeds, grains, and dried vegetables rather than a monotonous pellet.
  • Scatter-feed across the bedding to encourage natural foraging and slow eating.
  • Supplement with small amounts of fresh vegetables and occasional animal protein such as a mealworm or plain cooked egg.
  • Avoid sugary or citrus foods.
  • Provide unlimited fresh water from a bottle or bowl, plus cuttlebone or wood for gnawing.

Health

Signs of good health, and the common problems
  • Common issues include wet tail (a serious infectious diarrhoea, especially in young animals), overgrown teeth, obesity, and skin mites.
  • Older hamsters are prone to tumours and amyloidosis.
  • Sudden lethargy, wetness around the tail, or weight loss warrants urgent exotic-vet care.
  • Weigh your hamster regularly and check the teeth and rear.
  • Cheek-pouch impaction can occur from sticky or sharp foods.
  • Provide chews to keep the continuously growing incisors worn down.

Is this urgent?

4 warning signs and how fast to act, 2 of them right away

A hamster is small enough that a day of illness is a large fraction of its reserves. Do not wait a weekend out.

Go now

Watery diarrhoea, a wet or soiled tail area, lethargyGo now. Keep the hamster warm in transit. Severe infectious diarrhoea, most common in young hamsters, and often fatal within 48 hours untreated.
Now
Cold and unresponsive but not stiffWarm the hamster slowly with body heat and call. Do not assume it has died. Dwarf and Syrian hamsters can enter a torpor that looks like death when the room gets cold.
Now

Today

Not eating, or a full food store left untouchedCall today. A hoarding animal that stops hoarding has usually stopped eating too.
Today

Soon

A lump that is growing, or an open soreBook an appointment. Common in older hamsters and easier to address while small.
This week

Bar-biting, pacing and repetitive route-running are not personality. They are the signs of an enclosure that is too small.

This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it, and the time to find one is before you need one.

Bedding and substrate

4 safe, 1 with a caveat, 4 to avoid

Depth is the whole point. A hamster with 16 in of paper bedding behaves like a different animal to one with 1.2 in.

Safe

Dust-extracted paper bedding, 16 in deep or moreDeep enough to hold a tunnel that does not collapse: TVT and Swiss Animal Protection give 16 in, and never less than 8-10 in. This is the single biggest enrichment change you can make.
safe
Kiln-dried aspenMixes well with paper to give the burrow structure.
safe
Plain chinchilla bathing sand in a heavy dishFor coat condition. Sand, never dust.
safe
Hay and plain toilet paper for nestingSafe nesting material a hamster can shred itself.
safe

With a caveat

HempGood absorbency, but on its own it does not hold a burrow. Mix with paper.
with a caveat

Never

Fluffy cotton-wool nesting materialWraps around limbs and is swallowed. Repeatedly implicated in limb injuries and blockages in hamsters.
never
Pine and cedar shavingsAromatic oils; airway irritation and liver effects.
never
Raw corncobBlockage risk, and it moulds.
never
Scented beddingThe hamster's nose lives in it.

Is your enclosure big enough?

These are the smallest sizes that give good conditions, not legal minimums. More room is always better.

Minimum 11 sq ft of floor · 49 x 31 in

Every figure, and where it comes from

PDSA, Wood Green and Blue Cross print 39 x 20 in as the minimum for every hamster. This site uses the 11 square feet that TVT and Swiss Animal Protection recommend for a Syrian. Height is not checked, because the bedding, not climbing, is what needs it: 16 in of bedding takes solid sides about 20 in high and an enclosure at least 24 in tall.

The recognised standards do not agree on this one
TVT, the German veterinary association for animal welfare (golden hamster leaflet, 2025): 11 sq ft or more, and never less than 39 x 20 x 20 in. The figure this site uses. TVT says studies show hamsters do best from 11 square feet. Checked 2026-10-23.
Swiss Animal Protection STS: 11 sq ft, at least 24 in high. The same floor area. Checked 2026-10-23.
Fischer, Gebhardt-Henrich and Steiger, Animal Welfare (2007): 60 female golden hamsters in four cage sizes: Cages of 2, 2.7, 5.5 and 11 sq ft compared; welfare looked better at 11 sq ft. Bar-gnawing was longer and more frequent in the smaller cages. Checked 2026-10-23.
PDSA; Wood Green, The Animals Charity; Blue Cross (UK): 5.5 sq ft, for example 39 x 20 in, as a minimum. All three call it a minimum. PDSA and Blue Cross say bigger is better, and Wood Green that female Syrians may need more. Checked 2026-10-23.
Switzerland, Tierschutzverordnung (legal minimum): 2 sq ft, for example 24 x 12 in, with at least 6 in of bedding. A legal minimum, recorded for context. Checked 2026-10-23.
Austria, 2. Tierhaltungsverordnung (legal minimum, every hamster): 24 x 12 x 16 in, with at least 2 in of diggable bedding. A legal minimum, recorded for context. Checked 2026-10-23.
US Animal Welfare Act regulations, 9 CFR 3.28 (licensed dealers, exhibitors and research facilities only; there is no legal minimum for a pet cage): 10-19 sq in per hamster, by body weight. Recorded for context, not endorsed. The 121 sq in often quoted from it is the rule's figure for a nursing female with her litter. PetMD, by contrast, advises at least 6.5 sq ft of floor for a Syrian and 5 sq ft for dwarf and Chinese hamsters. Checked 2026-10-22.

What it really costs

Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.

Can a Syrian Hamster eat that?

Hamsters are granivores with an omnivorous streak. Scatter-feed a varied seed mix rather than filling a bowl with pellets.

Never (15)

AlcoholNo safe amount at any body weight on this site.

Rare treats (3)

AppleSugar. Fine for a Syrian as a rare treat, never for the diabetes-prone dwarf and Chinese hamsters. Remove the seeds. A piece the size of a pea, rarely.

Everyday foods (1)

Grain-based hamster mixA varied mix of seeds, grains and dried vegetables, scattered through the bedding so the hamster has to forage for it. About a tablespoon a day for a Syrian, less for a dwarf.

That food is not on our list. A hamster is small enough that a wrong food is a large dose. Leave it out.

Campbell's, winter white and Chinese hamsters are prone to diabetes. Treat every sugary food on this list as off the menu for every hamster except the Syrian.
